Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. This device series contains ESD protection and is tested per the following standards:
Human Body Model (HBM) per JEDEC standard: JESD22?A114.
Machine Model (MM) per JEDEC standard: JESD22?A115.
2. Latchup Current Maximum Rating: 150 mA per JEDEC standard: JESD78.
3. Measure on 1 inch sq. of 1 oz. copper area. R q JA is highly dependent on the PCB heatsink area. For example, R q JA can be 38 ° C/W on 1 inch
sq. of 1 oz. copper area on 4 layer PCB that has 1 single signal layer with the additional 3 solid ground or power planes. The maximum package
power dissipation limit must not be exceeded:
PD +
TJ(max) * TA
R q JA
with R q JA = 68.5 ° C/W, T J(max) = 100 ° C, P D = 1.09 W.
4. Moisture Sensitivity Level per IPC/JEDEC standard: J?STD?020A.
